Surface Coating of Metal Coil: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for new and existing sources that coat metal coil. The final rule implements section 112(d) of the Clean Air Act (CAA) and will require all new and existing metal coil coating operations that are major sources to meet HAP emission standards reflecting the application of the maximum achievable control technology (MACT).

The EPA has identified metal coil surface coating as a major source of hazardous air pollutant (HAP) emissions such as glycol ethers, xylenes (isomers and mixtures), toluene, and isophorone. For existing sources in the metal coil coating industry, the nationwide baseline HAP emissions are estimated to be 2,258 Mg/yr (2,484 tpy). We estimate that implementation of the final rule will reduce emissions from these sources by 1,198 Mg/yr (1,318 tpy), or approximately 53 percent. Since the emission limits for new and existing sources are the same, emission reductions for new sources are expected to be similar to the 53 percent emission reduction estimated for existing sources. Emissions of the HAP methyl ethyl ketone (MEK) are included in the emissions inventory and emission reduction estimates for this source category. MEK has been delisted since promulgation of the final rule.
